5 Evaluation of Nursing Best Practice Guidelines: Introduction In 1999, the Registered Nurses Association of Ontario (RNAO), with funding from the Ontario Ministry of Health and Long-Term Care, launched a multi-year project aimed at developing, pilot testing, evaluating and disseminating best practice guidelines (BPGs) for nurses. Seventeen BPGs were developed and launched by the RNAO during three cycles. Each BPG includes substantive, evidence-based recommendations for nursing practice and for organizational and policy change, as well as recommendations for nursing education. Details about the RNAO Best Practice Guideline Project may be obtained on the RNAO web site: A multi-site team designed a pre-post design evaluation to examine the process and impact of pilot site implementation of the BPGs. Both generic indicators and indicators specific to the BPGs were developed. This monograph is one of a series describing the measures used during this evaluation. The monograph is intended for evaluation teams that may be interested in using or adapting the interview schedules for their own evaluation purposes. In this monograph, we describe the development and psychometric properties of scales that measure organizational characteristics and provide recommendations for the administration, scoring and interpretation of these scales. The evaluation measures on organizational characteristics included in this monograph are: 1) Perceived Characteristics of Innovating for BPG Implementation, 2) Organizational Stability, 3) Organizational Support for BPG Implementation and 4) Organizational Culture for Change. The scales are included in the appendix. CHRU Monograph Series 1

6 Development of the Scales Background Two sets of instruments are described in this monograph: a) those used to measure organizational characteristics that were expected to influence the adoption of the Best Practice Guidelines and b) an instrument to assess the innovation characteristics of Best Practice Guidelines. In this section, instruments that were developed by the team are described. For those instruments that were adapted from the literature, the original sources for the instruments, the psychometric characteristics of the original versions of the instruments and the adaptations we made to existing instruments are summarized. Innovation characteristics The original Perceived Characteristics of Innovating (PCI) instrument included 43 items and 8 subscales (Moore & Benbasat, 1991), with a shortened version of 25 items. The PCI was designed to investigate how perceptions affect individual s actual use of technology based on Rogers' diffusion theory (1995). Domains of the original PCI included: 1) relative advantage (the degree to which the innovation is perceived as being better than its precursor); 2) compatibility (the degree to which the innovation is perceived as being consistent with the existing values, needs, and past experiences of the user); 3) complexity or ease of use (the degree to which the innovation is perceived as being difficult to use); 4) results demonstrability (the extent to which the uses of the innovation are apparent); 5) trialability (the degree to which the uses of the innovation may be experimented with before adoption); 6) voluntariness of use (the degree to which the use of the innovation is perceived as being voluntary); 7) image (the degree to which use of an innovation is perceived to enhance one's image or status in one's social system); and, 8) observability (the degree to which the results of an innovation are observable to others). The Cronbach s coefficient alphas for the original PCI subscales ranged from.71 (trialability) to.93 (relative advantage) (Moore & Benbasat, 1991). Construct validity of the original tool was confirmed via factor analysis and discriminant analysis of "adopters" versus non-adopters." We selected items from the first four scales of the short version of the PCI, with a view towards selecting those that were relevant for BPG implementation. Eight of the original PCI items were adapted for use in this study. Two new items were added which asked respondents to assess the extent to which the BPG fit with standard unit policies and procedures (unit compatibility). CHRU Monograph Series 2

7 Organizational characteristics Three domains of organizational characteristics were assessed: organizational stability, organizational culture for change, and organizational support for BPG implementation. The 7-item organizational stability instrument assessed significant organizational change that was expected to impact on implementation of the BPGs. For example, respondents are asked to rate on a 5-point scale to what extent staff cuts, absenteeism or hiring of new staff have occurred in their organization within the past six months. The organizational culture for change instrument assessed aspects of the organization that can influence changes in the organization such as morale, communication and workload. The degree of perceived organizational support for BPG implementation was assessed using five items from the support/resistance subscale of the Implementation Attitude Questionnaire developed by Schultz & Slevin, (1975). This measure was originally designed to assess the extent to which the respondent perceived adequate support from the organization in the implementation of a new information innovation (Robey, 1979; Robey & Bakr, 1978; Robey & Zeller, 1978; Rodriguez, 1977). Using a sample of salespeople being introduced to a computer-based information system, Robey (1979) reported acceptable internal consistency of the support/resistance scale (Cronbach s alpha =.74). This study also found a significant relationship between organizational support/resistance and objective measures of system use (r =.31, p <.01). In a more recent study of on-line learning for public health professionals, acceptable levels of internal consistency were found for organizational support for Best Practice Guidelines (Cronbach s alpha =.74) (Lockett, Edwards, Gurd & Simpson, 2003). Best Practice Guideline Development The RNAO developed BPGs during three cycles (see Figure 1). A multidisciplinary panel of nurses, administrators, nursing researchers, and specialists used a systematic approach to develop the best practice guidelines. Briefly, this process involved the review of evidence from current research, theory, and expert advice as well as extensive reviews of similar clinical practice guidelines. Recommendations were selected and the level of evidence supporting each recommendation was identified. Recommendations based on studies with meta-analyses were assigned the rating for the highest level of evidence while recommendations based on expert consensus opinion, in the absence of evidence from quasi-experimental studies were assigned the rating for the lowest level of evidence. Preliminary guideline recommendations and supporting documentation were then reviewed by several stakeholders. Each published BPG presents the guideline development process in detail and the specific stakeholders CHRU Monograph Series 3

8 who reviewed the guidelines. Upon completion of each cycle of guidelines, the RNAO invited health care organizations in Ontario to submit proposals outlining an implementation strategy. Successful organizations were provided with financial and administrative support for implementing the BPG. Figure 1.

Specific objectives of the evaluation of BPG pilot site implementation were to: Document the process of BPG implementation across project sites from the perspective of clinical resource nurses, staff nurses and nursing administrators; Determine the effectiveness of BPG implementation on changes in nursing practice, and selected clinical outcomes; Determine perceived utility and value of the BPG by clinical resource nurses, staff nurses and administrators; and, Examine factors that influence implementation of the BPG. Both qualitative and quantitative methods were used in the evaluation. A before and after design was used for cycles 2 and 3 evaluation, and a retrospective baseline for CHRU Monograph Series 4

9 cycle 1. Patient chart audits, patient interviews and nurse interviews were conducted at baseline and 6 months after implementation. For those BPGs where patient interviews were conducted or chart audits completed, patient eligibility criteria were set for each of the BPGs. A more detailed description of the evaluation design is available from the authors. Description of the Sample The sociodemographic characteristics of the sample of staff who completed the scales is shown in Table 1. The majority of respondents were registered nurses. However, in several organizations, registered practical nurses or staff from other disciplines were also involved in BPG implementation and thus were included in the sampling frame. A total of 747 participants are included in this analysis. Absent from this summary are those who participated in the evaluation of the Venous Leg Ulcers BPG and the Diabetes Foot Care BPG. Post-implementation data for the pilot site evaluations of these BPGs were not yet available at the time of this report. CHRU Monograph Series 5

13 Statistical Procedures Used in Psychometric Testing of Scale Items Data were analyzed using SAS 8.02 software ([SAS/STAT] software, version [8] of the SAS system for Windows. copyright by SAS Institute Inc., Cary, N.C., USA). For each scale, descriptive analyses were conducted to examine response patterns, skewness and kurtosis of the data. Internal reliability was assessed using Cronbach s coefficient alpha. Principal component analysis was used to describe the main axes of variance. We then conducted a factor analysis to determine whether all items in the scale (or sub-scale) loaded on the factor. Orthogonal rotation procedures were used to obtain the maximal amount of variance for all scales in this monograph except for the scale on Organizational Culture for Change. Varimax rotation, the most commonly used type of orthogonal rotation, provides a simple structure in factor analysis and was used in this study to facilitate interpretation of the factors. The goal of the factor analysis was to determine how many factors the items were located under as well as their significance. A more detailed description of factor analysis is included in the appendix. For the present study, we used the following measurement criteria and cut-offs: 1. Sampling Adequacy: Sampling adequacy predicts if the data is likely to factor. This is measured by the Kaisar-Meyer-Olkin (KMO) statistic. We used the most common cut-off, i.e..60 for the present study. When the value was less than the cut-off, we analyzed sampling adequacy by cycles, and included data from cycles where sampling adequacy criterion was met. 2. Factor Loading: An acceptance threshold of.40 for the loading was used in this study. 3. Eigenvalue: The eigenvalue for a given factor measures the variance in all the variables that is accounted for by that factor. The ratio of eigenvalues is the ratio of explanatory importance of the factors with respect to the variables. Kaisar s criterion is a common rule of thumb for dropping the least important factors from the analysis. The Kaisar rule is to drop all components with eigenvalues less than 1.0 which is the default in the SAS software and hence our cut-off criterion. 4. Cronbach Coefficient Alpha: This statistic was used to evaluate the internal consistency of each factor, and of all items in each scale. It is a measure of squared correlation between observed scores and true scores. The higher the alpha, the more reliable the factor. A Cronbach's alpha of.70 (rounded off) is generally considered adequate. CHRU Monograph Series 9

14 Psychometric Properties of the Scales Evaluation of Nursing Best Practice Guidelines: Descriptive Statistics Table 2 shows the timing of administration, what cycles were included in the analysis, the total number of respondents and the number of respondents with complete data for each of the scales. For example, the PCI for BPG Implementation was administered six months after implementation (post-implementation). The data for this scale included all three cycles since the versions used in all cycles were identical. Of the 601 respondents with post-implementation data, only 473 had complete data (that is, no blanks for all ten items administered during post-implementation). Table 3 (see the following page) presents the descriptive statistics for each item of the scales, including skewness and kurtosis. Table 2.

Missing Data As illustrated in the table above, non-response rates for individual items on the scales ranged from a low of 5.3% to a high of 23.2%. The item with the lowest missing data was "the morale of nurses in my unit/team is high" in the Organizational Culture for Change scale. The item with the highest non-response rate was the item "infusion of new money into organization" of the Organizational Stability scale. Results of Factor Analysis Results of the factor analysis for each of the scales in this monograph are presented below. Table 4 presents the final factor solutions. All factors demonstrated good internal consistency (Cronbach's alpha ranged from.69 to.89). For the Perceived Characteristics for Innovating for BPG Implementation, 10 items were initially included in the analysis with a two-factor solution. Nine items loaded on one CHRU Monograph Series 13

18 factor, and only one item loaded on the second factor. This item ( the BPG is too complicated to use by staff nurses ) had a loading of 0.91 on a second factor. This item was dropped since it was a single item factor and appeared to measure a different dimension. A two-factor solution was obtained for the scale on Organizational Stability. One-factor solutions were obtained for the pre and post-test versions of the Organizational Support for BPG Implementation. A three-factor solution was obtained for the initial 10 items of the Organizational Culture for Change. The third factor was a single-item factor and was dropped ( nurses exert group pressure on non-conforming workers": loading =.74). The three items in the second factor were dropped due to low internal consistency (Cronbach's alpha =.42). The items in this second factor were: "nurses carry out patient care procedures utilizing professional judgment" (loading =.62), "on my unit nurses often participate in decisionmaking" (loading =.61), and "nurses on my unit are strong advocates for patients and families" (loading =.49). The final scale has six items loading on one factor. Table 4.

21 Administration, Scoring and Interpretation Evaluation of Nursing Best Practice Guidelines: Administering the Scales The scales in this monograph are to be given to nurses directly involved in the implementation of the nursing BPG. These scales were not designed for patients or clients' significant others. Table 5 below lists the scales, the number of items per scale (proposed based on factor analysis), the types of rating scale used, approximate time to complete them, and suggested timing of administration. Note that for the scale on Organizational Support for BPG Implementation, there is a pre-test version and a separate post-test version. Table 5. Description of Scales on Scale Number of Items Type of Rating Approximate Time for Pre or Post Administration Perceived Characteristics of Innovating for BPG Implementation Organizational Stability Organizational Support for BPG Implementation Organizational Support for Change Scale 9 items 4 point Likert scale 7 items 5 point Likert scale 5 items 4 point Likert scale 6 items 4 point Likert scale Completion 3 min Post 2 min Post 2 min Pre and Post (different versions) 2 min Pre The scales were designed to be self-administered. It is recommended that nurses finish the scales in one session, or at the very least one scale in one sitting. If these scales are part of a larger battery of evaluation measures, adequate time and minimizing fatigue on the part of the respondents should be considered. For the evaluation of the pilot site implementation, it was found that time available and workload were barriers adversely affecting response rates. CHRU Monograph Series 17

22 Respondents should be provided with a covering letter explaining the purpose of the scales, the time required for completing the scales, and the confidentiality of the information. Scoring and Interpretation The scoring procedure for the scales involves adding the ratings for each item and obtaining a mean total score for each scale. If there are items left blank, cases either need to be excluded or missing values imputed before calculating the mean total score across all respondents. Negatively worded items are reverse-coded so that scores are in the same direction. In general, higher scores indicate higher levels of the indicator being measured. For the scale on Organizational Stability, higher scores indicate lower organizational stability. Conclusions Evaluation is a key step in determining whether the implementation of a nursing best practice guideline has improved patient outcomes through changes in nursing care. Evaluation findings may guide decisions about whether or not to support efforts to sustain or expand the use of specific practice guidelines in an organization. The scales in this monograph included: 1) Perceived Characteristics of Innovating for BPG Implementation, 2) Organizational Stability, 3) Organizational Support for BPG Implementation and 4) Organizational Culture for Change. Scores from these scales can provide insights on factors that can influence the implementation of the BPGs. This monograph presents the development and psychometric properties of these scales based on our pilot site evaluation of the implementation of BPGs from cycles 1 to 3. Scales included in this monograph demonstrated adequate levels of internal consistency. Scales demonstrated adequate response variability. Missing response patterns suggest that respondents were least familiar with items listed in the Organizational Stability scale. Scales are recommended for use in similar evaluation studies.

25 Primer on Factor Analysis Factor analysis is a technique used mainly to reduce the number of variables, and to detect structure in the relationship between variables. Factor analysis is commonly used in developing and refining instruments, by identifying how many factors or domains a questionnaire has, and which items go together i.e., the items have high loadings on a factor. A typical factor analysis answers four major questions: 1. How many factors are needed to identify the pattern of relationship among given variables? 2. What is the nature of those factors? 3. How well do the inferred factors explain the variables they define? 4. How much unique variance is explained by the observed variables? 1. Sampling Adequacy: Sampling adequacy predicts if the data is likely to factor. This is measured by the Kaisar-Meyer-Olkin (KMO) statistic. This value ranges from 0 to 1.0 and a value of at least.60 should be obtained to proceed with the factor analysis. 2. Factor Loading: This is purely arbitrary and varies by research context. In instruments with Likert type scales, the following criteria are often used: low loading for less than.40, moderate between.40 and.60, and high for more than.60. Factor loadings range from -1 to +1. The sign reflects the direction of relationship between the item and the factor. 3. Eigenvalue: The eigenvalue for a given factor measures the variance in all the variables that is accounted for by that factor. The ratio of eigenvalues is the ratio of explanatory importance of the factors with respect to the variables. Kaisar s criterion is a common rule of thumb for dropping the least important factors from the analysis. The Kaisar rule is to drop all components with an eigenvalue less than 1.0 which is the default in the SAS software. 4. Rotation: Rotation is commonly used to obtain a simple and more understandable factor structure. There are generally two types of rotation: orthogonal and oblique rotation. Orthogonal rotation is commonly used since it facilitates interpretation. An orthogonal rotation provides a simpler factor structure and assumes that the factors are uncorrelated. Varimax rotation is the most widely used orthogonal rotation. Oblique rotation is used when factors are correlated factor structure and interpretation of the factors is often more complex.
